I tried to get people to do it early.
But yes, way too late now to mail it in and hope it's received on time and accepted.

I would have recommended ballot drop boxes anyway, since it's more direct and they're picked up daily or even multiple times a day.
But at this point, even that is unwise.

If you procrastinated and waited this long to do anything, you should really be voting in person if at all possible. Ideally early voting, if it's an option, since the lines will still be less than election day (and who knows if you wait till then if bad weather or some emergency keeps you from going to vote).
If you absolutely must do the mail in ballot now, bring it to an official drop box, like...right fucking now, or tomorrow.
Check online frequently to see the status, that it was received and then that it was approved. If it's not received or is rejected, you need to allow yourself time to find out and rectify the problem (probably by voting in person, sorry) before the close of the polls on Nov. 3rd.
